520U overview

Description

Control and monitor 8 optically isolated inputs and 8 (SPDT) high-current Form C relay outputs via any USB connection with the SeaI/O-520U.

Inputs can range from 5V-30V DC and optical isolation protects the computer and other sensitive equipment from voltage transients and ground loops that are common in industrial environments.

The high-current Form C relays can switch up to 6A loads at 250V AC and 100V DC. Form C relays can be wired for either normally open or normally closed operation.

The SeaI/O-520U is powered from your 9-30V DC source, or select from a variety of Sealevel power supply options.

Communicate with the SeaI/O-520U using the Sealevel SeaMAX API software libraries or use any Modbus RTU compliant device. Sealevel's SeaMAX software drivers and utilities make installation and operation easy using Linux, Windows 2000, XP, Vista and Windows 7 operating systems.

Expand your I/O network with SeaI/O "N" series products. SeaI/O modules are available with Reed and Form C relays, optically isolated inputs, TTL interfaces, A/D and D/A functionality. Up to 246 additional expansion modules can be added using convenient pass-through connectors.

The SeaI/O-520U integrates a patent-pending SeaLATCH USB port, which is fully compatible with standard USB cables. When used with the included USB cable with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure connection to the device and prevents accidental cable disconnection.
